Interesting stuff there, but I'll deal with this a little later. I agree maybe you should cut and paste it in the workshop section.

Ours don't have the air pump, that thing you're thinking of would be the cruise control vacuum tank?

The Impulse air pump would be the same thing that came on TF/TG Geminis except the Gemini pump is driven by a belt off the engine. It pumps fresh air into the exhaust ports on the head to cheat emission tests..

Huh, I didn't know your Piazzas didn't have the air injection system like our Impulses did. I could have sworn I saw parts of that system on some of the Piazza Turbo pictures I have seen on this forum.

Thanks bugle. Maybe I should leave that in if retaining the factory CC, or delete if incorporating impulserocket's system.

LOL! I love Bugle's:

Not that I want to hijack, and not that it's something I am in to - meaning I have never had reason to investigate air pumps etc (all my road vehicles are pre-1973 ADR)...

But I had thought that the pump actually lessened emissions rather than converting emissions. I know that is the same thing, but maybe it's best explained by my anti-emissions view at the time.
When emission legislation first appeared, many systems were add-ons, eg charcoal canisters, air pumps, retarding ignition by 3°, etc.
I felt that was a waste since it decreased fuel economy and performance. Essentially it meant more exhaust gases per mile albethey better (ie, less CO and NOx).
It was understandable at the time since manufacturers could not change their engine designs overnight.

Since then however the proper "front end" engineering has occurred - ie, better combustion efficiency, sealed fuel and breather systems, etc. And EFI has added to that through its dynamic compensation of fuel-air mixtures and delivery matching to engine loads & RPM (unlike chokes and pedal to the metal on carby systems).

I do wonder if a true unrestrained market would have beaten legislation to emission standards, but vested interests exempted that (eg, the plethora of other fuel savers etc that were bough and shelved; GM preventing GMH from developing (mechanical) fuel injection in 1957).


Nevertheless I found Bugle's "cheating" comment amusing - though in hindsight it's probably not so funny. IMO it is a valid description no matter how it is viewed - other than the bottom line where it did reduce the targeted hazardous emissions (though now we add CO2 to that list even though its hazard was known and predicted in the 1800s and observed as early as 1976).
Alas such descriptions - or even "bullshit" - can be applied to so many things these days. Luckily - or sadly - most people don't seem to realise...


Not that I meant to hijack, nor get (socially) political... :ANAL:

Maybe you talking about "INJECTOR BLOWER". At Impulse on the right side.

Nice find. I don't understand Japanese but I can see what appears to be a carbon fibre bonnet. Is that page offering them up for sale? It's a pitty the bonnet is the early version. Impulserocket and I have the later version.

Nah, the injector blower is something totally different. This sits between the rear of the engine and the firewall.

Probably only carbon fiber shell (no frame) - 84,000yen
Full carbon fiber hood - 126,000yen
FRP hood - 42,000yen

below is written: we will make any car part from carbon fiber, if they do not have it (except the hood).

126,000 yen= about AU$1,330.00. Hmmm I'd probably go for it at that price. I might email them to see if they've done any later style bonnets. (Ah..er. Now to learn Japanese 101...ah yes. Konnichiwa...that's all I know)

Using Firefox?

Get the Translate This add-on.
Though I installed it ages ago, I never read the instructions (of course!) but a few weeks ago I right-clicked a block of text and and chose Translate "<blocked>" by mistake. (So that's what it does!)
Since then I have used it heaps - even those Jap links above.
The translation seems amazingly accurate and sensical.
When for this reply I checked what add-on it was, I also saw that it translates whole pages. (Damn - I require another 50 seconds to read instructions!)

I also have the gTranslate add-on, but I don't know what it does.. (LOL??)


Now that's what I call convergence!

I run Firefox so I'll give it a go. I already sent a message to them in English last night, but I won't know if they understood it. I'll wait and see. Either way I'm thinking shipping costs will be horrendous, not to mention possible radioactive contamination. Who knows, maybe the hoods will glow at night. How cool would that be. lol.

Informative video, but I have no inclination to do this myself. Firstly I don't have the time, I don't have the space, and considering our hoods will require two moulds (outer and inner skin with embedded latches, hinge and strut mounting points, etc) it will be much better if I leave it to the experts.
